“…For instance, Mike Wu, Brian Richards, and Ron Baecker (2004) used PD with a group of six individuals with memory loss (amnesia) to develop a computational tool to help with the problem of disorientation. In another research project, PD was used with people with aphasia in the development of an Enhanced with Sound and Images (ESI) planner for the personal digital assistant (PDA) (Moffatt, McGrenere, Purves, & Klawe, 2004). Julia Galliers, Stephanie Wilson, Abi Roper, Naomi Cocks, Jane Marshall, Sam Muscro, and Tim Pring (2012) also engaged potential users with aphasia, and conducted a series of workshops in which five participants used gestures (rather than spoken or written language) to express ideas about soware and paper game prototypes and to provide evaluations of them.…”
